QY single-stage multistage centrifugal oil pump
The QY type oil pump series is redesigned on the basis of the original Y type oil pump series. It is a new product developed to adapt to the upgrading of energy-saving equipment, and has the following characteristics : 1. Bearing body parts The original 35,50,60 bearing bodies are replaced by 45,55,70 bearing bodies respectively, which improves the reliability. The hydraulic model of high efficiency and energy saving is adopted in the hydraulic flow components, which is 5-8 percentage points higher than the efficiency of the original Y-type oil pump ; In order to maintain continuity, the structure type, installation size and performance parameter range of AY type oil pump are the same as those of Y type oil pump, which is convenient for the renewal and transformation of old products ; 4, parts generalization degree is high, the standard parts for several series of products ; 5. Material selection and refining, mainly I, class materials, bearing body and other parts increased to cast steel, cast iron, for cold regions, open-air use, marine provides favorable conditions ; 6, bearing air cooling, air cooling, water cooling three, according to the different use of the pump temperature selection. Air cooling is particularly suitable for areas with water shortage or poor water quality. QY type oil pump can be used in petroleum refining, petrochemical and chemical industry and other places to transport oil, liquefied petroleum gas and other media without solid particles.
DJ multi-stage centrifugal oil pump
DJ multi-stage centrifugal oil pump is suitable for petrochemical plants. It is used to transport non-corrosive oil and petroleum products without solid particles and with viscosity less than 120 cm. The temperature of the transported medium should not be higher than 105 °C. The allowable inlet pressure is 0.6 MPa.
